Alpinestars Tech 5 boots combine a lightweight, abrasion-resistant microfiber chassis with a multi-panel construction designed for motocross and off-road riding. The microfiber upper provides water resistance, durability, and a consistent fit over extended use, while the synthetic polymer toe box and polymer panel construction support abrasion resistance and contact with the bike.
A medial-facing biomechanical pivot system connects the lower and upper boot sections to provide front and rear flexibility with structural support. Extended accordion flex zones and ergonomically profiled TPU buckle straps promote front flexion, while soft poly-foam around the ankles and collar helps absorb shock. A full interior textile lining contributes to riding comfort.
The one-piece TPU-injected dual-compound foot shell is reinforced with an internal metal shank and harder-compound co-injected toe reinforcement for impact and abrasion resistance. The buckle closure system uses polymer and fiberglass buckle arms with high-impact aluminum bridge closures. Memory and quick-release locking functions, a self-aligning design, and replaceable buckles support convenient, precise closure and secure performance. This Alpinestars boot is offered in a black, white, red, and yellow colorway in size 8.
